. drive their respective cruising speed nozzles independently or to open and close them together and admit niotorfluid to all the working passages of theturbines.

The exhaust fluid from turbines i enters chambers 23 in the supply-heads 7 of turbines .2, from which it flows through valve-controlled nozzles to the working passages of the turbines, being directed against the forwarddrivin buckets 24 on the bucket-wheels 25. I use luid-uctuated motors "36 to open ant close these nozzlespthe actuatin fluid being conducted to the several motors y pi cs '27, leading through the head and chain er i7 and shell 16. These pi es register witharou orts 28 in a contro ler-casing 29, such as is t escribed more fully in said patent, a rotutable valve-shell 30 being mounted therein and having a row of ports 31, which register with the pipes .27 or with a row of ports 3'2 in the casing 29, which connect with pipes 33. leading to the i'luiil-unotors 34 in the head 13 of the adjacent reversing-turbinc. A piston 35 in shell 30 sets as a valve to admit the tluiihpressure supplied to casing '29 throu h pipe 36 and admitted to the interior of t ie shell by a port 37 to one or more of the ports 31 When pressure is admitted to a controlleriipe, all the motors cou led up therewith wi 1 move the valves whic 1 they operate to close the nozzles under their control. therefore form the shell 30 so that it admits pressure to one of the groups of passages '28 or 32, while controlling the admission or exhausting of pressure through ports 31 to the other row of pipes. in this manner when turbines 2 are operating the controller mechanisin will cut oil all motor fluid from admission to turbines 3, where it would act a ainst the buckets 38 to reverse shefts'S, and, vice versa,when turbines 35 are operating the valvecontrolled nozzles through which the exhaust from turbines 1 enters turbines 2 will be closed. Since turbines 1 exhaust through these nozzles. and since turbines 2 are sup,- plied throu h them, it follows that when all are closed t eso turbines will be cut out of service, the how of motor fluid through the one being stopped and the admission of motor fluid to the other being interrupted. It follows also that by varying the number of these nozzles held open the cooperation of these turbines maybe controlled, so that they shafts with varying powers or velocities. Hence a single mechanism controls not only the operation of a terward and a. reversing turbine, but also the cooperation of the whole set of turbines. This feature of my present invention l claim as broadly novel and without limitation to the specific construction of the turbines or their overning means.

The shell 30 is rotated by a crank 40, and

the piston-valve 35 is actuated by a rack 41 l l l i a l i turbine connected u and pinion O erating-rods 43 and 44 for the piston and s ell, respectively, lead to #1 point from which the controller mechanisni for the ad 'scent turbine 1, which may have similar operating devices 45 and 4-6, can be manipulated.

Moton'luid pressure is supplied to ports 18 of turbines 1 through pipe 47, which has branches 48 leading to the supply-ports 49 for the reversing-turbines. These latter turbines 3 may, if desired, be provided with stage-valves, so that when the steam-supply is cut oil their several wheel-compartments may be exposed to the atmosphere through drain-pipes leading from the bottom of said com mrtinents for draining out all water 0 condensation accumulating therein, or, when the exhaustipes and condenser'arrangenients are sucli as to permit the draining of these turbines these sta ewe-Ives may be dispensed with, as when t e condenser andexlmust pipes are disposed below the level of the turbine-wheels.

The propellers of the two sets of turbines normally rotate in opposite directions.

The independent control or each of the turines enables me to produce varying driving ell'ects, both as to speed and power, and also to operate them in opposition to each other to a sist in steering the vessel? Having thus-described my invention, what i claim as new; and desire to protect by Let 1. in a set of marine turbines, a highressure, tvvo-speed, forward-driving tur ine, and a low-pressure turbine operatin in series therewith, independent shafts or said turbines, and s reversing-turbine connected to one of said shafts.
